Application August 31,1939, Serial No. 292,939 4 Claims. (Cl.210-131l This invention relatesto a cleaner adapted for installation in the water cooling line of aninternal combustion engine, preferably between the water pump andradiator outlet thereto, being of such construction as to remove allundesired matter in the water such as excess water pump grease, rust"and other sediment.

It is particularly aimed to provide a structure which may beinexpensively made of non-corrosive parts, one having a removablecartridge, one having means whereby it may be attached in a novel andadjustable manner with minimum parts, and one which is generallyimproved and simplified as will appear hereinafter and become apparentfrom a consideration of the following description and accompanyingdrawing.

In said drawing- Figure 1 is a view showing the cleaner in sideelevation, as applied in an automobile cooling system, the latter beingshown fragmentarily;

Figure ,2 is a plan View of the parts primarily constituting theinvention;

Figure 3 is a vertical sectional view taken on the line 3--3 of Figure2, and

Figure 4 is a horizontal section taken on the line 4-4 of Figure 3.

Referring specifically to the drawing wherein like reference charactersdesignate like or similar parts, the invention comprises a preferablycylindrical container or tank l0 having a bottom wall ll secured inwatertight relation thereto. At the top, tank l0 preferably has a shortinwardly extending flange i2.

Within the tank ill, located above the bottom wall II and parallelthereto is a shelf or support 13 for a removable cartridge generallydesignated l4. Said support or shelf I3 is soldered or otherwise securedin place at its margin as at l5 to the tank l0 and it has a centralopening l6 so that water may pass through the cartridge.

Said support or shelf l3 divides the interior of the tankinto a lower orwater receiving chamber l1 and an upper filtering or water outletchamber I 8. The device is adapted to be connected in the water coolingsystem of an internal combustion engine as best shown in Figure 1. Inthat figure, l9 designates the engine, 20 the radiator, I

2| the outlet conduit from the radiator, 22 an inlet conduit to thewater jacket of the engine and 23 a return conduit from such waterjacket to the radiator. As a result, the device is installed between thewater pump and radiator outlet to the pump. .It will be understood thatthe arrangement of the conduits and of the water system parts generally,in different cars or automobile will vary, and in some instances will bebuilt special, and that the arrangement of the conduits, position of thecleaner and the like will vary accordingly. Removable connections arepreferably provided between the tank or container Ill and the conduits2| and 22. 1

Reverting to the cartridge I4, it consists of a. central perforatedtubular drum 24 and an outer perforated tubular drum 25 providing aspace filled with any conventional filtering material, for instance,asbestos, steel wool, mineral wool or slag, glass wool, with or withoutthe inclusion of granular material like diatomaceous earth, limestone orthe like. Such cartridge also has an upper end wall 26 having an annulardownwardly extending flange 2'! provided with screws or the like 28enabling removal of the top for removal and replacement of the filteringmaterial. A spacer 29 is preferably soldered or otherwise fastenedcentrally to the top wall 26, aiding in centering the central drum 24.At the lower end, a bottom wall 30 is provided, having a marginal flange3i soldered to the outer drum 25 and having a central flange or collar32 soldered to the central drum 24 and extending snugly but removablyinto the opening 16. A gasket 33 surrounds the flange or collar 32 andengages wall 30 and shelf 1 3, to insure passage of the water throughthe cartridge from chamber i! into chamber I8 and outlet through theconduit 22.

Said tank or container I0 is removably. engaged by a generally U-shapedclamping frame or bracket 34, having a bridge 35, disposed above andacross the top of the container l0, depending legs 36 at the sides ofthe container and inwardly extending feet or lugs 31 at the lower endsof the legs on which the container rests.

A cover plate 38 extends over the top of the container to close the sameliquid tight and maintain the cartridge in place and a gasket 39 isinterposed as shown. Such cover plate 38 is maintained in place with therequisite pressure, by the action of a screw 40 passing through bridge35 at a fixed nut 4| thereon, the screw having a handle or extension 42to facilitate its manipulation.

It will be noted that throughout the major portion of the length of thelegs 36, they are offset at 43 from the container, to provide spaces 44,through which "an attaching band or clamp 45 passes. Like the frame orclamp 34, the band 45, is preferably made from a single strip of metal.Band 45 has terminal portions 46, through which a bolt 41 passes and isoperable to bind the band around the container, at any desired angle andelevation. One of the terminals 46 is extended to form an attaching lugas at 48. The latter may be engaged with any convenient part, and forinstance a. cylinder head'bolt of the engine i9, which may be passedthrough an opening 49 in the lug.

It will be clear that in operation, the circulating water within thecooling system of the engine cock in the bottom of the automobileradiator 20 serves as a drain for the cleaner and the complete system.Also, it will be noted that a gasket is not required at the'top of thecartridge between the cover plate.

Various changes may be resorted to provided they fall within the spiritand scope of the invention.

I claim as my invention:

1. A cleaner for a water cooling comprising a container, filtering meanstherein, a support within the container for the filtering meansproviding a receiving chamber and an outlet chamber, a mounting framecontaining the container, a cover over the container and filteringmeans. clamp means adjustably mounted on th frame and engageable withsaid cover plate, said frame including legs at the sides of thecontainer, said legs having offset portions providing spaces between thesame and container, an attaching bracket surrounding the container andpassing through said spaces.

2. A cleaner for the water cooling system of an engine comprising acontainer closed at the bottom and open at the top, a shelf within thecontainer spaced above said bottom to provide a receiving chamberbeneath the same and an outlet chamber above the same, said shelf havingan opening therethrough, a cartridge within the outlet chambercontaining filtering material, said cartridge having an inlet memberextending into said opening, a cover plate over the open. end of thecontainer and engaging the cartridge, means securing the cover plate inposition, comprising a screw, a generally U-shaped frame having a bridgethrough which said screw passes, legs depending from the bridge at thesides of the cont ainer having feet disposed under the container.

3. A cleaner for the water cooling system of an engine comprising acontainer closed at the bottom and open at the top, a shelf within thecontainer spaced above said bottom to provide a receiving chamberbeneath the same and an outlet chamber above the same, said shelf havingan opening therethrough, a. cartridge within the outlet chambercontaining filtering material, said cartridge having an inlet memberextending 7 into said opening, a cover plate over the open end of thecontainer and engaging the cartridge, means securing the cover plate inposition, comprising a screw, a generally U-shaped frame having a bridgethrough which said screw passes,
